The Freedom Caucus is a hard-right group of House members who were largely responsible for blocking the bill to undo President Barack Obama's Affordable Care Act. The bill was pulled from the House floor Friday in a political defeat for the president.

Trump initially focused his blame on Democrats and predicted a dire future for the current law.

Before the bill was pulled, Trump tweeted at the Freedom Caucus, saying Planned Parenthood funding would continue if they blocked the legislation.

Meanwhile, a Trump tweet Saturday night promoted a Fox News show that somewhat attacked House Speaker Paul Ryan, R-Wisconsin — the biggest backer of the health care bill. On Sunday morning, Ryan's advisers told NBC News that was merely "a fluke, not a conspiracy." They also said that "Speaker Ryan and the president are in a great place."
